AccentCL: Robust Accent Classification with Incremental Expansion
Mu-Ruei Tseng, Waris Quamer, Ghady Nasrallah +1
Accent classifiers are typically trained with a fixed label inventory and cannot accommodate new accent categories as new data becomes available. Moreover, accented speech corpora…
VOSSA: Voiceprint Optimization for Streaming Speech Architectures
Mu-Ruei Tseng, Waris Quamer, Ghady Nasrallah +1
Real-time voice conversion (VC) systems commonly rely on pretrained speaker embeddings from automatic speaker verification (ASV) models. While effective for speaker discrimination,…
PHONOS: PHOnetic Neutralization for Online Streaming Applications
Waris Quamer, Mu-Ruei Tseng, Ghady Nasrallah +1
Speaker anonymization (SA) systems modify timbre while leaving regional or non-native accent cues intact, which is problematic because such cues can reveal a speaker's first-langua…
TVTSyn: Content-Synchronous Time-Varying Timbre for Streaming Voice Conversion and Anonymization
Waris Quamer, Mu-Ruei Tseng, Ghady Nasrallah +1
Real-time voice conversion and speaker anonymization require causal, low-latency synthesis without sacrificing intelligibility or naturalness. Current systems have a core represent…
